Abstract
The method of dual-way pseudo ranging is used in navigation constellation crosslink to implement precise orbit determination and time synchronization. The accuracy of dual-way pseudo ranging is directly influenced by delay variation in transceiver. Based on the illustration of the conception and estimating model of delay, a real-time on-line closed loop calibration method of transceiver absolute delay is advanced. The experiment shows that the accuracy of this method is better than 0.3 ns.
